Question:

Successive discounts of $25\%$ and $20\%$ are equal to a single discount of what percent? / $25\%$ और $20\%$ की क्रमिक छूट किस एकल छूट प्रतिशत के बराबर होगी?

1.
$45\%$ / $45\%$
2.
$42\%$ / $42\%$
3.
$40\%$ / $40\%$
4.
$38\%$ / $38\%$

Correct Answer: $40\%$ / $40\%$

Single equivalent $= 25 + 20 - \frac{25 \times 20}{100} = 45 - 5 = 40\%$. / एकल समतुल्य छूट $= 25 + 20 - \frac{25 \times 20}{100} = 45 - 5 = 40\%$।
